TON 618: Meet the Largest Monster in the Universe

TON 618 is the largest black hole ever discovered — with a mass estimated at 66 billion times that of the Sun.
Its event horizon (the boundary beyond which nothing can escape) is so massive, it’s 30–40 times wider than our entire Solar System,
including even the distant Oort Cloud.
But here’s the most mind-blowing part:
The light we see from TON 618 has been traveling for 18.2 billion years — meaning this cosmic giant existed long before Earth, the Sun, or even the Milky Way.
This isn’t just a black hole.
It’s a monument to how vast, ancient, and mysterious our universe truly is.
